Hi,

I couldn't find a PGA with gain of 1, 2, 4, 10, 16, 32. Something similar to Microchip MCP6S21. Can you help to advise?

    Hello,

    We have similar devices to the MCP6S21, although they do not offer gain of 10; and are not pin-to-pin compatible:

    The PGA112 and PGA116 are single-ended input, and single ended output programmable gain amplifiers with binary gains (1, 2, 48,16, 32, 64,128) with SPI interface, supporting analog supply range of 2.2V to 5.5V.  The PGA112 offers a 2-channel mux and the PGA116 offers a 10 channel mux.

    Other single-ended input, and single ended output programmable gain amplifiers with scope gains (1, 2, 5, 10, 20, 50,100, 200) are the PGA113 and PGA117 with SPI interface, supporting analog supply range of 2.2V to 5.5V.  The PGA113 offers a 2-channel mux and the PGA117 offers a 10 channel mux.

    Thank you and Kind Regards,
